4 Claims.

This invention relates to toilet or closet bowl construction, the primary object of the invention being to provide a closet bowl having an auxiliary float chamber at the rear thereof, communicating with the closet. bowl and water inlet pipe so that if stoppage occurs in the closet bowl, the water will flow into the float chamber, operating means therein, for cutting off the flow of water to the bowl, thereby avoiding any possibility of the flooding or overflowing of the closet bowl and the inconvenience resulting therefrom.

An important object of the invention is to provide a device of this character including a float operating within the float chamber and connected with the valve Within the flush tank of the closet bowl by means of a flexible member for automatically cutting ofi the flow of water to the closet bowl with the rise of the float within the float chamber.

Still another object of the invention is to provide a device Of this character having a removable cover forming a part of the float chamber, which may be readily removed should it be desired to repair or adjust the apparatus.

Referring to the drawings:

Figure 1 is a vertical sectional view through a closet bowl and flush tank associated therewith, illustrating the invention as forming a part of the bowl.

Fig. 2 is a sectional view taken on line 22 of Fig. 1.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is a vertical sectional view through the closet bowl illustrating the normal discharge of the water into the bowl.

Fig. 5 is a vertical sectional view illustrating the position of the float and valve prior to the seating of the valve caused by a choked condition of the discharge pipe of the bowl.

Referring to the drawings in detail, the reference character 5 indicates the closet bowl which, in accordance with the present invention, is provided with a float chamber 6.

The reference character 1 indicates the water inlet passageway formed at the top of the bowl, the passageway I having a discharge opening 8, discharging water directly into the bowl. A plug indicated at 9 forms a part of the bowl and passageway and may be removed, should it be desired to gain access to the float chamber 6 for purpose of repair or adjustment.

Formed in the plug 9 is an opening l0 through which a quantity of water passes into the float chamber 6, as the water passes into the bowl 5. Adjacent to the bottom of the float chamber 6 is a passageway II that establishes communication between the bowl -5 and float chamber 6, so that water from the float chamber 6 will be directed into the passageway l I and into the bowl 5 preventing water from the bowl passing into the float chamber 6.

Secured within the bottom of the float chamber 6, are the bearings I3 in which the ends M of the roller l5 operate. The roller l5 provides a guide for the chain I B which is shown as extending thereunder, the chain I 6 being secured to the float I! that operates in the float chamber 6.

The chain I6 is of a length to extend through the opening I 8 formed in the bottom of the passageway 1, from where it passes upwardly through the connecting pipe l9 between the bowl and flush tank 20, where it extends into the flush tank. 20 and connects with the valve 2| that controls the passage of water from the flush tank.

Thus it will be seen that when the float I1 moves upwardly within the float chamber due to the water level rising within the float chamber, the chain It will be pulled under the roller I5 resulting in the valve 21 being pulled downwardly into engagement with its seat, cuttin 01f the flow of water from the tank 20 to the pipe l9 and into the closet bowl 5 which would otherwise tend to flood the closet bowl.

From the foregoing it will be seen that due to the construction shown and described, I have provided a closet bowl which is equipped with a float chamber in which a float operates, the float being connected to the usual flush tank valve to close the valve when the water level in the closet bowl and float chamber reaches a predetermined level.

Having thus described the invention what is claimed is:

1. In a flushing closet bowl having a flush tank, a body portion, a water inlet pipe connecting the body portion and flush tank, a valve in the flush tank controlling the flow of water to the body portion, a float chamber forming a part of the body portion, said body portion and water inlet pipe having openings establishing communication between the float chamber, water inlet pipe and body portion, whereby water enters the float chamber as the water level rises in the body portion, a float operating in the float chamber, and a flexible member extending through the water inlet pipe connecting the float and valve, closing the valve when the flexible member is tightened,

upon movement of the float beyond a predetermined point within the float chamber.

2. In a flushing closet bowl having a flush tank, a body portion, a water inlet pipe connecting the body portion and flush tank, a valve in the flush tank controlling the flow of water to the body portion, a float chamber forming a part of the body portion, said water inlet pipe having an opening through which-water passesinto the float chamber, said body portion having a-passageway at the base of the float chamber establishing communication between the bowl and float chamber, whereby water passes from the float chamber, a guiding member within the float chamber, a chain extending through the water inlet pipe and passing into the float chamber operating under the guide member, a float-t'o' whichthe chain tank controlling the flow of water to the body portioma float chamber forming a part ofthe body portion and having passageways establishing communication between theinlet pipe, closet bowlflanu float chamber, ag'uide roller mounted, within the" bottom of the float chamber, a chain operating through the'inlet'pipe and moving under the roller in contact therewith, a float operating within the float chamber said chain being connected with the float and valve of the flush tank whereby movement of the float moves the valve to its closed position cutting off the flow of water to the bowl.

4. In a flushing closet bowl having a flush tank, a body portion, a water inlet pipe connecting the body portion and flush tank, a valve operating in the flush tank controlling the passage of water from the flush tank through the water inlet pipe, a float chamber forming a part of the body portion, said body portion having water passageways through which water enters the float chamber, a rotary guide member mounted within the float chamber, and a chain operating through the inlet ipe, said chain moving under the guide member in-contact therewith, a float connected to one end of the chain, the opposite end of the chain being connected with the valve whereby upward movement of the float within the float chamber operates the valve, stopping the flow of water intotliefloat chamber and closetbowli I v BARTHOLOMEW E.
